For the First Lady's final State of the Union appearance in Washington, D.C., Tuesday, the 51-year-old modeled a marigold wool crepe dress by Narciso Rodriguez. According to The Week magazine, the dress has already sold out! Her shoulder length, side sweep bang hairstyle sealed the look. Michelle was seated in the House of Representatives gallery, where she received a warm welcome from attendees.

Michelle's sleeveless banded dress sold out online before the night was over. The look was originally priced at $2,095 at Neiman Marcus, but was later reduced to a more affordable $628.

The First Lady famously wore Narciso Rodriguez when President Barack Obama was elected in 2008. Past designers who have dressed the First Lady for appearances at Barack's State of the Union addresses include Michael Kors in 2015, Azzedine Alaïa in 2014, Jason Wu in 2013, Barbara Tfank in 2012, Rachel Roy in 2011, Isaac Mizrahi in 2010 and Narciso Rodriguez in 2009.
